Preparing an Upgradable System

A profile is given below, first four items are musts for upgradable systems, the rest are for additional setups. Read carefully. Intel chipsets have more chance for success.

• Main System
• PC EFI V9 Bootloader
• One of the Decrypters
• One of the SMBIOS Enablers
• It is better to use the stock kernel. If any custom kernel is selected then you will need to replace the System.kext with the one in /Library/Temp after applying the update.
• For PS2 mouse/keyboard it is better to select x86 ACPI driver instead of PS2 driver.
• Speedstepping support may be problematic for upgradable systems without Disabler. But you can use it safely with Disabler.
• GMA950-a will fail after update, GMA950-b or efi string should be selected for such systems.
